ZO'KLZZ whom it may concern/.

Be it known that I, JOHN H.VANDERSLICE,

a citizen of the United States, and a resident of Ooatesville, Pennsylvania, have invented certain Improvements in Flanging-Machines,

of which the following is a specification.

The object of my invention is to prevent the buckling of plates during the process of flanging. This object I attain by using, in connection with the ordinary hanging-rolls of a Hanging-machine, separate antibucklingrolls which press upon the plate during the fianging process.

In the accompanying drawings, Figure l is a side view, partly in section, of a flangingmachine, illustrating my improvement. Fig. 2 is a transverse sectional view on the line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional view on the line 3 3, Fig. 2. Fig. 4 is a section on the line 4. 4, Fig. 3. Fig. 5 is a detail view showing the upper antibuckling-roll pressing upon the plate during the last part of the flanging process, and Fig. 6 is a view showing the roller used when a flat plate is being flanged. p

A is the bed-plate of an ordinary flangingmachine, on which is mounted the flanginghead B. This flanging-head can be moved longitudinally on the bed by any suitable op- 0 crating means. On the head is a quadrant b,

in which travels a slide B, carrying a flanging-roll b. This slide B is moved in the quadrant by means of a worm-wheel c on a vertical shaft O, which is geared to an operatingshaft 0, the worm-wheel c engaging teeth on a segmental slide B.

D is a central shaft stepped in a suitable hearing A and driven by gearing d cl from a driving-shaft D. Carried by this vertical 4o shaft D is a head D upon which the plate to be flanged is clamped. The head in the present instance has a rounded upper surface, and the clamp E is shaped to conform with the head, so as to clamp a dished plate a, as shown in Fig. 1.

It will be noticed that the clamp is less i diameter than the head, and this allows a certain portion of the plate to be exposed beyond the edge of the clamp, so that the anti- 5o buckling device can act. The clamp E is held in place by a vertical shaft or piston-rod E. Heretofore it has been difficult to prevent the I plate buckling during the flanging process, but by my invention, which I will now proceed to describe, I can flange a plate so as to 5 frame H can be adjusted on its pivot by means of an operating-shaft J, pivoted at j to the carriage F and having a threaded portion which passes through a nut h, pivoted to a hearing h, secured to the frame H. By turning the hand-wheel j on the shaft J the frame H can be adjusted to any angle desired. Each side plate of theframe H has a slot 72. there- I in, and passing through the slot are bolts 6 e, which can be so adjusted as to lock the frame securely in its adjusted position or can be turned back, so as to allow it to be adjusted by the shaft J. On the end of the shaft G is a worm-wheel g, with which engages a wornnSo Z on the shaft L, provided with ahand-wheel Z. This shaft is mounted in bearings on an extension F of the carriage F, as clearly shown in Figs. 2 and 3. On turning the shaft L the slide I can be raised or lowered. On the slide are two bearingsM and N. Secured to the bearing M is a stud m, carrying a roller M. This roller in the present instance is conical in shape andis arranged so as to rest under the outer edge of the plate .to be flanged, as shown in Fig. l. The bearingN is inclined and has an inclined stud a, carrying a roller N, which is arranged to bear upon the upper edge of the plate during the last partof the fianging process, .so as to keep .the plate 5 firmly to its seat on the head. Thebearings are secured to the slide I by bolts or other suitable fastenings,'and theyican be removed and bearings and rollers differing in shape can be mounted on the slide in their stead, rco

the shape of the rollers and the character of the bearings depending upon the form of the plate to be flanged. When a flat plate is to be flanged, then a single roller may be used, as in Fig. 6. On the shaft G is a grooved wheel G, to which is secured the rope or chain g?, from which is suspended a counterweight g which counterbalances the slide I, the bearings M and N, and their rollers.

The operation is as follows: If, forinstance, a dished plate is to be flanged, as shown in Fig. 1, it is clamped upon the head D by the clamp D and the flanging-rollerb is adjusted so as to bear upon the overhanging portion of the plate, as shown in said figure, and as the plate is turned the roller is gradually lowered, so as to cause the overhanging portion of the plates to be turned down to form the flange. During this operation the edges of the plate have a tendency to buckle or crimp, and to prevent this I so' adjust the roller M, which is mounted on the opposite side of the flange to the flanging-roller, that it will bear against the under side of the plate and will tend to remove the buckles as they are formed by the flanging-roll. The roller Mis lowered as the" fiange is formed, so than the said antibuckling-roller will suppor t'the outer edge of the plate and take the buckles out as they are. formed. When the flange has been turned down to such an angle that the roller M will not operate, then it is removed from position and the roller N is I brought into contact with the upper edge of the plate at the point where the plate is turned down over the head D as the plate hasa tendency to buckle and elevate the edges during the last part of the process and while the flanging-roller is making the finishing pressure to bring the flange to the proper angle.

I find by the above-described apparatus plate, a slide on said carriage having rollers,

said rollers being relatively apart from one another, with means for moving said slide whereby either of the rollers may be brought 'into contact with the plate operated upon,

substantially as described.

2.. The combination in a flanging-machine, of a head, means for clamping a plate on said head, means for flanging said plate, a carriage independent of said flanging means, a frame pivoted to said carriage, a slide mounted on said frame, means for adjusting the frame, means for adjusting the slide, and a roller carried by the slide arranged to bear upon the plate to be flanged, substantially as described.

3. The combination in a flanging-machine, of a head, means for clampinga plate on said head, means for flanging said plate, a carriage, a frame pivoted to said carriage, a slide mounted on said frame, means for adjusting the frame, means for adjusting the slide, with two rollers mounted on the slide independently of the flanging means, one arranged to bear upon one side of the plate and the other to bear upon the opposite side of the plate, substantially as described.

4. The combination in a flanging-machine, of a head, means for clamping a plate on the head, means for flanging said plate, a carriage, a frame pivoted to the carriage, a shaft for adjusting said frame, a slide mounted on the frame, a rack on said slide, an operatingshaft, a gear-wheel on said shaft meshing with the teeth of the rack, and a roller carried by said slide, substantially as described.

5. The combination in a flanging-machine, of a head, means for clamping a plate 011 the head, means for flanging said plate, a carriage, a frame pivoted to the carriage, a shaft for adjusting said frame, a slide mounted on the frame, a rack on said slide, an operatingshaft, a gear-wheel on said shaft meshing with the teeth of the rack, and a roller carried by said slide, with a wheel on the said shaft, a counterbalance-weight suspended from said wheel to counterbalance the slide and its roller, and means for operating said shaft, substantially as described.

6. The combination in a flanging-machine, of a head, means for clamping a plate to the head, means for flanging said plate, with two rollers independent of said means, bearings therefor, said rollers being so mounted in respect to the plate to be flanged that during the first part of the process of flanging one roller can be adjusted to bear against the under side of the plate, and during the last part of the process of flanging the other roller can be adjusted to bear upon the opposite side of the plate, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN H. VANDERSLICE.
